Hair plugs represent one of the earliest attempts at surgical hair restoration, and many people still wonder about their effectiveness and growth potential. As a hair transplant surgeon who has seen the dramatic evolution of hair restoration techniques, I want to provide a comprehensive explanation of what hair plugs are, how they work, and whether they actually grow after being transplanted.
What Are Hair Plugs?
Hair plugs were the primary method of hair transplantation from the 1950s through the 1980s. This outdated technique involved removing circular sections of scalp containing 10-20 hairs each from the back of the head and implanting these “plugs” into the balding areas. The plugs were much larger than today’s micrografts and often created an unnatural, doll’s hair appearance.
The term “hair plug” has become somewhat controversial in modern hair restoration circles because it carries negative connotations of poor results. Today’s advanced techniques bear little resemblance to these early attempts, though many people still use the term when referring to any type of hair transplant.
Do Hair Plugs Actually Grow?
Yes, hair plugs do grow after being transplanted – that was never the problem with the technique. The hairs in these plugs continued growing because they were taken from the permanent donor zone at the back and sides of the scalp, where hair is genetically resistant to balding. This fundamental principle of donor dominance remains true in modern hair transplantation as well.
The issue with hair plugs wasn’t whether the hair grew, but rather how it grew. The problems included:
Unnatural grouping of too many hairs together
Visible scarring around each plug
Obvious contrast between pluggy areas and thinning areas
Poor distribution that didn’t mimic natural hair growth
Difficulty styling the hair to conceal the plug appearance
While the hair did grow, the overall aesthetic result often looked artificial and drew attention rather than providing a natural-looking solution.
Why Hair Plugs Looked Unnatural
Several factors contributed to the artificial appearance of hair plugs:
Size and Density
Each plug contained many more hairs than natural follicular units (which typically have 1-4 hairs). This created unnatural clumps rather than the gradual thinning seen in natural hairlines.
Placement Patterns
Plugs were often placed in obvious rows or grids rather than the irregular, staggered patterns of natural hair growth. This geometric arrangement made the transplants easily detectable.
Scarring
The large circular wounds created visible scarring around each plug, especially as the surrounding native hair continued to thin over time. These scars became more apparent as patients aged.
Hair Direction
The angle and direction of hair growth from plugs often didn’t match the natural flow of the patient’s existing hair, creating noticeable inconsistencies.
The Evolution Beyond Hair Plugs
Modern hair transplantation has completely moved away from the plug technique through several key advancements:
Follicular Unit Transplantation (FUT)
This method involves:
Removing a thin strip of donor scalp
Dissecting it into natural follicular units under microscopes
Implanting these tiny grafts in a way that mimics nature
Follicular Unit Extraction (FUE)
This approach:
Extracts individual follicular units directly from the scalp
Uses tiny punches that leave minimal scarring
Allows for precise placement of natural-looking grafts
Microscopic Dissection
Advanced magnification enables technicians to:
Preserve natural follicular groupings
Minimize damage to grafts
Sort hairs by size for strategic placement
Refined Placement Techniques
Modern methods create:
Irregular, staggered hairlines
Proper angulation matching natural growth
Gradual density changes from front to back
Seamless integration with existing hair
How Modern Transplants Differ From Plugs
Today’s hair restoration procedures differ from old plug methods in nearly every aspect:
Graft Size
Modern grafts contain 1-4 hairs (natural groupings) versus 10-20 hairs in plugs
Scarring
FUE leaves nearly invisible dot scars; FUT leaves a thin linear scar – nothing like the obvious circular plug scars
Naturalness
Contemporary techniques create completely undetectable results that even hair stylists can’t identify
Long-Term Appearance
Modern transplants age gracefully with the patient rather than becoming more obvious over time
Styling Options
Patients can wear their hair long or short without revealing evidence of transplantation
Do Old Hair Plugs Continue Growing?
For patients who had plug procedures decades ago, the hairs in those plugs will continue growing as long as:
The original grafts were taken from the permanent donor zone
The hair follicles weren’t damaged during transplantation
No scarring compromised the blood supply to the grafts
The patient hasn’t developed conditions that affect all hair growth
However, the problems with plug appearance often become more pronounced over time as:
Surrounding native hair continues to thin with age
Skin changes make plug scars more visible
Fashion trends favor shorter hairstyles that reveal plug marks
The contrast between plugs and thinning areas increases
Repairing Old Hair Plugs
Many patients seek corrective procedures to address pluggy results. Options include:
Plug Removal
Surgically removing obvious plugs and redistributing the hair as individual follicular units
Camouflage Transplanting
Adding modern micrografts around plugs to soften their appearance
Laser Hair Removal
Reducing the density of plugs by selectively removing some hairs
Scalp Micropigmentation
Using medical tattooing to help blend pluggy areas with thinning regions
Combination Approaches
Using multiple techniques together for optimal improvement
Why Modern Techniques Are Superior
Today’s hair transplantation methods offer significant advantages:
Natural Appearance
Results are completely undetectable as transplants
Minimal Scarring
Almost invisible donor area marks with proper technique
Better Survival Rates
Advanced handling preserves more grafts
Long-Term Results
Designs account for future hair loss progression
Styling Freedom
Patients can wear any hairstyle without concern
Higher Patient Satisfaction
Natural-looking outcomes boost confidence
The Science Behind Hair Growth in Transplants
Whether discussing old plugs or modern grafts, the biological principle remains the same:
- Hairs from the permanent donor zone maintain their growth characteristics when moved
- These follicles continue their normal growth cycles (growing, resting, shedding)
- The hair shaft is produced by living follicle cells beneath the skin
- Adequate blood supply supports ongoing hair production
- Transplanted hairs respond to the same hormonal influences as their original location
This explains why both plugs and modern grafts continue growing – the difference lies in how natural the growth appears.
Factors Affecting Transplanted Hair Growth
Several factors influence whether transplanted hair (plugs or modern grafts) will grow successfully:
Donor Hair Quality
Healthier, more robust hairs have better growth potential
Surgical Technique
Gentle handling preserves follicle integrity
Recipient Site Preparation
Proper depth and angle promote good blood supply
Patient Healing Ability
Individual factors affect graft survival
Post-Operative Care
Following instructions optimizes results
Underlying Health Conditions
Some medical issues can impact hair growth
Common Misconceptions About Hair Plugs
Several myths persist about hair plugs:
Myth: The Hair Doesn’t Grow
Truth: The hair does grow, but often looks unnatural
Myth: Plugs Fall Out Over Time
Truth: Successful plugs continue growing indefinitely
Myth: All Transplants Look Pluggy
Truth: Modern techniques create completely natural results
Myth: Plugs Can’t Be Fixed
Truth: Many correction options exist
Myth: Plugs Were Always Obvious
Truth: Early results often looked decent before surrounding hair thinned
Recognizing Outdated Techniques
- Patients should be wary if a clinic offers:
- Large graft sizes (more than 4 hairs per graft)
- “Punch graft” procedures
- “Standard” rather than custom hairline designs
- No microscopic dissection
- Limited before-and-after photos
- No mention of follicular unit transplantation
These may indicate outdated approaches that could yield pluggy results.
Choosing a Modern Hair Transplant
- To ensure natural-looking results, look for:
- Surgeons specializing in follicular unit transplantation
- Use of microscopes for graft preparation
- Before-and-after photos showing hairlines up close
- Customized hairline designs
- Detailed explanations of techniques
- Positive patient testimonials
This helps avoid the problems associated with old plug methods.
The Future of Hair Restoration
While hair plugs are obsolete, the field continues advancing with:
- Robotic assistance for precise harvesting
- Stem cell research to multiply donor hair
- Improved graft preservation solutions
- Enhanced growth factors to boost results
- Less invasive techniques with faster recovery
These innovations promise even better outcomes while making the procedures more accessible.
Conclusion
While old-style hair plugs did grow after transplantation, their unnatural appearance made them undesirable compared to today’s advanced techniques. Modern hair transplantation has completely transformed the field, offering completely natural-looking results that grow seamlessly with a patient’s existing hair. The key differences lie in the size of grafts, placement artistry, and surgical precision – not in whether the transplanted hair grows.
For patients living with outdated plug results, various corrective options exist to improve appearance. More importantly, anyone considering hair restoration today can be confident that modern methods bear no resemblance to the plug procedures of the past. With careful surgeon selection and proper expectations, today’s hair transplants can provide undetectable, permanent results that restore both hair and confidence.
